For ±the 12V output model, output voltage can be set to
24V single output by making the COM terminal and TRM
terminal open. And output voltage can be set to 30V single
output by making the COM terminal open and connecting
the TRM terminal to the -Vout terminal.

1-3. Output voltage adjusting func-
tion (adding external resistance)
(1.5-10W type)
Output voltage can be varied in the range shown in the fig-
ure below by connecting a resistance (Ra, Rb) between the
TRM terminal and the -Vout terminal or between the TRM
terminal and +Vout terminal.
Note that when the output voltage is set high, derating
of output current is necessary according to the maximum
power.

Calculating output voltage Vout (V) from connected resis-
tance Ra, Rb (k)
Adding a resistance Ra between TRM terminal and -Vout
terminal, to set the output voltage high
*1 Vout = 3.3 + 9.59/(32+Ra)
*2 Vout = 5.01 + 17.64/(17.8+Ra)
*3 Vout = 12.01 + 50.53/(16.9+Ra)
*4 Vout = 12.02 + 53.55/(18+Ra)
Adding a resistance Rb between TRM terminal and
+Vout terminal, to set the output voltage low
*5 Vout = 3.3 - 15.53/(39.6+Rb) [Rb ≧ 62]
*6 Vout = 5.01 - 52.55/(31.8+Rb) [Rb ≧ 160]
*7 Vout = 12.01 - 431.1/(57+Rb) [Rb ≧ 620]
*8 Vout = 12.02 - 968.5/(103+Rb) [Rb ≧ 1500]
Calculating connected resistance Ra, Rb (k) from set out-
put voltage Vout (V)
Adding a resistance Ra between TRM terminal and -Vout
terminal, to set the output voltage high
*1 Ra = 9.59/(Vout-3.3) - 32
*2 Ra = 17.64/(Vout-5.01) - 17.8
*3 Ra = 50.53/(Vout-12.01) - 16.9
*4 Ra = 53.55/(Vout-12.02) - 18
Adding a resistance Rb between TRM terminal and +Vout
terminal, to set the output voltage low
*5 Rb = 15.53/(3.3-Vout) - 39.6
*6 Rb = 52.55/(5.01-Vout) - 31.8
*7 Rb = 431.1/(12.01-Vout) - 57
*8 Rb = 968.5/(12.02-Vout) - 103
